The present invention relates to a process for dichromatic or trichromatic dyeing or printing.

The object on which the present invention is based was to discover a process for dyeing or printing natural or synthetic polyamide fibre materials with dyes which are suitable for combination according to the dichromatic principle, and in particular according to the trichromatic principle.

It has now been found that this object can be achieved according to the invention by the process described below. The dyeings thus obtained achieve the object described. In particular, the resulting dyeings are distinguished by a uniform colour build-up with a simultaneous constancy of shade in various concentrations and good combination properties, and have a good levelness and no dichroism.

The amines and coupling components mentioned above for the individual dyes of the formulae (8) to (13) together additionally contain 1 to 3 radicals T₁.

The diazotization of the amines is as a rule carried out by the action of nitrous acid in aqueous-mineral acid solution at a low temperature, for example 0° to 15° C., and the coupling to the particular coupling component is carried out at acid or neutral to weakly alkaline pH values, in particular at a pH of 2 to 8.

Furthermore, dyes of the formulae (8) to (13) in which T₁ is a radical of the above formula (7a) or (7b) can be obtained by condensation of a dye containing amino groups with a cyanuric halide and a compound of the formula H-V₂ or H-V₃. The individual condensation reactions here can be carried out under the conditions described above for the preparation of the anthraquinone dyes.

The present invention furthermore relates to fibre-reactive anthraquinone dyes of the formula ##STR44## in which X₁ is fluorine or chlorine and X is the radical ##STR45## and Hal is bromine or chlorine, and the dye of the formula (24) contains two sulfo groups in total, ##STR46## in which X₁ is fluorine or chlorine and Z is the radical --CH═CH₂ or --CH₂ --CH₂ --Y and Y is --Cl, --OSO₃ H or --OCO--CH₃, and ##STR47## in which X₁ is fluorine or chlorine and Z is the radical --CH═CH₂ or --CH₂ --CH₂ --Y and Y is --Cl, --OSO₃ H or --OCO--CH₃.

X₁ is preferably chlorine.

Hal is preferably bromine.

The radical Y is preferably --Cl or, in particular, --OSO₃ H.

Preferred dyes are those of the formula (26) or, in particular, of the formula (24).

The present invention furthermore relates to processes for the preparation of the dyes of the formulae (24) to (26).

The process for the preparation of the dyes of the formula (24) comprises reacting compounds of the formulae ##STR48## with cyanuric fluoride or cyanuric chloride.

The process for the preparation of the dyes of the formula (25) comprises reacting compounds of the formulae ##STR49## with cyanuric fluoride or cyanuric chloride.

The process for the preparation of the dyes of the formula (26) comprises reacting compounds of the formulae ##STR50## with cyanuric fluoride or cyanuric chloride.

The particular reactions can be carried out under the conditions described above for the preparation of the anthraquinone dyes of the formula (1).

The dyes used in the process according to the invention for dichromatic or trichromatic dyeing or printing and the anthraquinone dyes of the formulae (24) to (26) according to the invention exist either in the form of their free sulfonic acid or, preferably, as salts thereof.

Salts, are, for example, the alkali metal, alkaline earth metal or ammonium salts or the salts of an organic amine. Examples are the sodium, lithium, potassium or ammonium salts or the salt of mono-, di- or triethanolamine.

The dyes used in the process according to the invention and the anthraquinone dyes of the formulae (24) to (26) according to the invention can comprise further additives, for example sodium chloride or dextrin.

The process according to the invention for dichromatic or trichromatic dyeing or printing and the anthraquinone dyes of the formulae (24) to (26) according to the invention can be applied to the customary dyeing and printing processes. In addition to water and the dyes, the dye liquors or printing pastes can comprise further additives, for example wetting agents, antifoams, levelling agents or agents which influence the nature of the textile material, for example softening agents, additives for flame resistant treatment or soil-, water- and oil-repellent agents, as well as water-softening agents and natural or synthetic thickeners, for example alginates and cellulose ethers.

The amounts in which the individual dyes are used in the dyebaths or printing pastes can vary within wide limits, depending on the desired depth of shade, and in general amounts of 0.01 to 15% by weight, in particular 0.1 to 10% by weight, based on the goods to be dyed or the printing pastes, have proved advantageous.

Dyeing, which is carried out, in particular, by the exhaust method, is preferred.

Dyeing is preferably carried out at a pH of 3 to 7, in particular 4 to 6. The liquor ratio can be chosen within a wide range, for example from 1:5 to 1:50, preferably 1:5 to 1:30. Dyeing is preferably carried out at a temperature of 70° to 110° C., in particular 80° to 105° C.

To increase the wet fastness properties, and to remove any non-fixed dye, an after-treatment can be carried out at a pH of, for example, 8 to 9 and a temperature of, for example, 75° to 85° C.

The dyes used in the process according to the invention and the anthraquinone dyes of the formulae (24) to (26) according to the invention are distinguished in dichromatic or trichromatic dyeing or printing by a uniform colour build-up, good affinity and fixing properties, good constancy of shade, also in various concentrations, good fastness properties and, in particular, very good combination properties.

The process according to the invention for dichromatic or trichromatic dyeing or printing and the anthraquinone dyes of the formulae (24) to (26) according to the invention are suitable for dyeing and printing both natural polyamide fibre materials, for example wool, and synthetic polyamide fibre materials, for example polyamide 6 or polyamide 6,6, and are suitable for dyeing or printing wool and synthetic polyamide blend fabrics and yarns. Dyeing or printing of natural polyamide fibre materials, in particular wool, and preferably wool which has been given a washing machine-resistant treatment, is preferred. The textile material mentioned can exist here in widely varying forms of processing, for example as fibre, yarn, woven fabric or knitted fabric, and in particular in the form of carpets.

Level dyeings with good allround properties, in particular good fastness to rubbing, wet processing, wet rubbing and light, are obtained.

In the following examples, parts are parts by weight. The temperatures are degrees Celsius. Parts by weight bear the same relation to parts by volume as the gram to the cubic centimeter.

EXAMPLE 1

0.57 part of the yellow-dyeing dye of the formula ##STR51## 0.53 part of the red-dyeing dye of the formula ##STR52## and 0.65 part of the blue-dyeing dye of the formula ##STR53## are dissolved in 200 parts of water, and 0.5 part of sodium sulfate, 0.1 part of a levelling assistant (based on the condensation product of a higher aliphatic amine and ethylene oxide) and 0.5 part of sodium acetate are added. The pH is then brought to a value of 5.5 with acetic acid (80%). The dyebath is heated at 50° C. for 10 minutes, and 10 parts of a woollen fabric are then added. The bath is heated to a temperature of 100° C. in the course of about 50 minutes and dyeing is carried out at this temperature for 60 minutes. Thereafter, the bath is allowed to cool to 90° C. and the dyed goods are removed. The woollen fabric is washed with hot and cold water and then spun and dried. A brown dyeing which has good light and wet fastness properties and a good levelness is obtained.
